No results posted yet for this study

Summary

To analyze the clinical predictability of transverse arch expansion achieved with two clear aligner systems (Invisalign, Angel Aligner-Angel Aligner Pro) by comparing planned and achieved dental movements through digital model analysis at different treatment stages using a repeatable and reproducible digital measurement technique.

Conditions

  • Narrow Palate

Interventions

DEVICE

Invisalign expansion

Transverse dentoalveolar expansion was performed according to the virtual treatment planning established in the aligner software. Orthodontic movements were progressively achieved through the sequential use of the planned clear aligner (an aligner per step).

DEVICE

Angel Aligner

Transverse dentoalveolar expansion was performed according to the virtual treatment planning established in the aligner software. Orthodontic movements were progressively achieved through the sequential use of the planned clear aligners (an aligner per step).

DEVICE

Angel Aligner Pro

Transverse dentoalveolar expansion was performed according to the virtual treatment planning established in the aligner software. Orthodontic movements were progressively achieved through the sequential use of the planned clear aligners (an initial softer aligner worn for 7 days, followed by a second, more rigid aligner worn for 3 days before progressing to the next stage in the treatment sequence)
